I like that this is portable, so I can check all of my air cooled equipment with it. Helps to dial in the idle RPM, and set the governor however high you want. I'm also using it on a go-kart to see what RPM the centrifugal clutches are applying and also determining if I have optimal gearing for the track I'm using it on. I don't have it permanently hooked up so I don't use the hour meter or the reminders, so I can't comment on those features, but the RPM part is exactly what I needed.

Diesen Drehzahlmesser verwende ich um unsere Geräte zu warten und nach deren Saison quasi noch einmal zu überprüfen.Die Wartungsfunktion welche beinhaltet ist (Stundentimer) verwende ich nicht, da müsste ja an jedem Gerät ein Drehzahlmesser angeschlossen bleiben. Die Laufzeit ist für mich eher uninteressant, eher Drehzahl an sich.Wir haben zwei Rasentraktoren, einen Rasenmäher, eine Rüttelplatte, eine Schneefräse etc.Bei so vielen Fahrzeugen / Geräten ist es doch praktisch die Leerlaufdrehzahl bestimmen zu können, gerade nach einer Saison noch mal schnell schauen ob alles in Ordnung ist.Dafür verwenden wir diesen Drehzahlmesser und er ist super dafür geeignet.Ich hoffe die Entscheidung die Schneefräse jetzt Ende Februar einzumotten rächt sich nicht noch.Die Funktionen haben alle ihre Berechtigung, wir brauchen nur stand- und maximale Drehzahl, das klappt hervorragend, dafür volle Sterne!
